Serial No. 347.540.

To all whom a: may concern:

citizen of the United States, residing at llamilton. in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Machines for Stacking lieebBlanks, of which the following description. in connection with the accompanying drawings, is a specification, like I reference characters on the drawings indieating like parts in the several figures.

This invention relates to machines for stacking heel blanks to facilitate handling such blanks in the manufacture of boots and shoes, or in the course of the production of f rapidity as he is usually able by glancing at Be it known that I, Josnrn ll. Porn, a

such blanks as separate articles of mannfacture.

The invention will be herein described. with reference to tbc handling of top lifts. but it will be understood that substantially all of its "tenures are capable of embodiment in machines for arranging other hccl blanks in a symmetrical order. for example heels instead. of top lifts.

Top lifts prior to their attachn'ient to heels are now commonly ('(llllplTSStdl to give them certain improved charm-ticristics. the

being considerable variation in the quality I v 1 towed to be upon one side, and I have acof the lifts before compression and some lack of uniformity existing after coinprcssion. quality is the appearance of the grain side,

The most important criterion of the presence of wrinkles, for example, upon this side detracting from the quality of the supplied in disorder to the worlunen for the grading operation. Ingrading the lifts the workmen find it desirable to first arrange 1 them in line, flesh side to grain side and then deal the successive lifts into their appropriate places. this course ermitting them to be rapidly sorted. A s'illecl Workman can in this way sort theta witl'i great lifts in order; flesh side to grain side, so as to render unnecessary a preliminary arrangement of the lifts by hand prior to sorting them. To this end, in the present embodiment of the invention, I provide a receiver which is arranged to permit lifts from a compressing machine to be fed into itsm-cessively', and is constructed to sustain a number of lifts in a parallel relation face to face. llileans are provided for transferring into position in said receiver suecessivc lifts from the dies of the compressing machine, which in the compressing machine shown are discharged laterally, curved end :t'orcmost from operative relation to said dies. The lifts compressed in this machine have a uniform position in the die cavity, andthe transferring means may therefore be arranged to act uniforlnly upon the lifts and subject them to one and the same treatment, in order that when positioned in the receiver they will face in the same direction and have their respective edge faces in cordingly arranged in their path mechanism for raising them on end and arranging them in the receiver in an upright position. The lifts may conveniently be introduccd into the receiver at one end, the contents of the receiver being moved along automatically at the introduction of each lift. A. convenient construction for positioning the lifts in the receiver comprises a carrier arranged at the entrance to the receiver and constructed to be moved from an approximately horizontal position, in which it receives a lift into a vertical position. in its movement into vertical position the carrier raises the lift and places it on end within the receiver, the arrangement being such that the return of the lift with the carrier as the carrier moves into its original position, is prevented. To facilitate removal of the blanks from the machine the receiver herein illustrated is formed in a plurality of sections. The section farthest removed from the point of introduction of the blanks, and which is here inafter termed an auxiliary receiver, is arranged for detachment from the machine and accordingly constitutes a convenient means for transferring the blanks from the machine to the point of use.

Other features of the invention will be hereinafter described and defined in the claims.

In the drawings:l*igure 1 is a view in perspective of the more importantparts of a machine embodying my invention. Fig. 2 is a view in perspective of a device which may be employed to store the lifts. Fig. 3 is a view in side elevation with parts in section of a portion of the machine. Fig.4 is a View in'perspcctive of a portion looking from helow in Fig. 1. Fig. 5 is a view in perspective of a detail.

in the embodiment of the invention here- "in described, the blanks to be arranged in order are top lifts received from a compressing machine of the construction shown in United States Letters Patent No. 776,787, dated December 6, 1904. In this compressor a head 1 is raised and lowered once in each cycle of operations, and an ejector 2 is advanced into the position shown in Figs/1 an 3 at approximately the end of thedownward movement of the head 1 to push the compressed top lift from the top lift plate curved end foremost and flesh side uppermost. Heretofore, the lifts when (liSClliLlQ'Gd from the compressor have entered a chute leading to a convenient; receptacle.

In embodying my invention in a machine for arranging top lifts discharged for a compressor of the construction shown in said Letters Patent. the compressor is preferably not'materially changed. Certain parts of this compressor above referred to, in themselves without novelty, cooperate with certain novel elements and devices shown herein to arrange the top lifts in the manner deen'tjembodiment of the invention contributes to securing auniform arrangement of the toplifts in the receiver.

In the present embodiment of the inventlon a bracket 4 is secured to the rear face of ,the compressor frame and is provided with a horizontal bore at its upper end to receive a rod 6, held in said bore by a set screw 8.

Arranged adjacent to each end upon the rod as 0: Mamba-10, 12,- rigidly secured to the rod,

ottomof the receiver is secured. The p to 16 may conveniently be of wood, and its upper face is concave in transverse section, to receive upon it the curved ends of the lifts. The sides ofthe receiver are formed of thin metal plates 18, 20 and arms 22, 23, 24 and25 secured to said plates respectively sustain theni in position, said arms being supported by the rod 6. As shown the lower ends of the arms 22, 24 are formed as collars 26, 28 rotatably sustained by the shaft 6 and the lower ends of the arms 23 and 25 are similarly provided with collars 27, 29 bearingupon said shaft. Segmental bevel gears 32, 30 are formed on the bottom of the collars 26, 28, respectively, with their teeth facing, and a bevel gear 34 is arranged between and in engagement with said segmental gears, said gear being pi oted on the hub 10. The collars 27 and 29 are provided with similar opposed segmental gears 31, 33 in mesh. with a bevel gear sustained upon the hub 12. Springs 36, 37 are connected to said arms 22 and 24., and 23 and 25 tending to hold the sides of the receiver inwardly. It will be seen that the gear connections be tween the arms 22 and 24, and 23 and 25 insure that the two arms of each pair will move equally in opposite directions, and

hence a symmetrical arrangement of the sides 1.8, 20 with relation to the center of the receiver is insured. As shown, the gear 34 is provided with an operating handle 370 and the hub 10 provided with perforations 38 arranged at intervals and adapted to receive a removable pin 40, projecting into the path of the handle 370. it will be seen from the drawings-that the spring'3li holds the handle 370 against the pin 40, so that the position of the pin 40 in the series of perforations 38 determines the position of the sides 18 and 20 and hence the width of the receiver.

A carriers-2 is secured to a horizontal shaft 44 pivotally sustained by the bracket 4 at the entrance to the receiver. A coiled spring 46 secured to the shaft 44 at one end and to the bracket 4 at the other holds the carrier 42 yieldingly in its lower position, shown in Fig. 3. A quadrant 48 is fixed upon the shaft 44 at one end and is against and traveling with the head through.

a part of its path of movement, and that as the head descends the spring 46 returns the carrier to; itsrlower, position. .It. will be;

j in this figure.

by the ejector 2.

noted by an inspectionof Fig. 3 that the path of vertical reciprocation of the head intersects the arc-shaped path through which the carrier 42 travels and that the carrier will be pressed by the spring 4t; against the head, and will receive motion from it until the head has risen far enough to take up the slack in the chain 50, shown The carrier is thus maintained by the spring 46 in lift-receiving po sition with relation to the head during a portion of its movement in order to insure the reception by it of all lit'ts discharged In the raised position of the carrier 4-2 said carrier is approximately flush with the end of the side walls 18, 20. The quadrant 48 is adjustably secured upon the shaft 44, as by means of a set screw +9, to permit the raised position of the carrier 42 to be controlled accurately. The carrier is provided with ribs 52 which are secured thereto by set screws )ivotal adjustment of said ribs 52 about the set screws being permitted. The ribs 52 serve to position the top hit upon the carrier deflecting it into a central position, in case the ejector 2 does not ad- Vance the top lift centrally of said carrier. A stop 52' upon the carrier 42 lnnits rearward movement of the blank upon the car rier. Extending from the forward end of each of the sides 18, 9.0 are curved guides 54, extendin forwardly and downwardly, and arrangec to engage the sides of a blank, yieldingly in the upward movement of the carrier 42 and guide the blank into the end of the receiver. The carrier is providtal with apertures 56 to receive the guides 51+, and said guides are held together at their lower ends by the device shown in Fig. 5 corn rising a rod 58 having a series of note test 60 at one end and a head to at the other. The notches U0 engage an aperture in one of the extensions 54, said aperture being enlarged at its upper end as shown to permit disengagement of the rod and relative adjustment of the guides 54 in the manner desired.

An upwardly projecting lug 6 L is carried by the bracket 4 and projects above the bottom of the receiver at its entrance. Flat springs (56 are arranged on the inner side of each of the guides 54-. The springs (36 and lug 64 serve to prevent return of a blank after its introduction to the receiver,

the springs 66 yielding in the upward movement of the blank and the carrier 42 advancing the blank oily the lug 64. The use of the springs 66 and' .tg (34 is not essential, as the sides 18 and 20 may be adjusted relatively to engage frictionally the edges of the blank and hold it from return movement. The sides 18"and 20 and guides 54 are preferably so adjusted that the lower ends of said guides are arranged slightly farther apart than the upper ends so that the top lift will pass freely between the lower ends of said guides when said lift is advanced by the ejector As the top lift is raised by the carrier 4: its edges are engaged by the guides at and the lift is thus guided into the open end ol the receiver.

The receiver is preferably provided with a removable extension in which the blanks may be carried to the place desired. A convenient construction of auxiliary receiver is that shown comprising two sections (38, 70 formed of wood, and having their inner t'aces shaped to provide a trough approximately U'shaped. The sections (38, 70 may be as long as may be conveniently handled and are connected by means permitting their adjustment to vary the width of the cavity formed between them. As shown, to each end of the sections (38 and 70 are secured plates T2 having bosses 73 provided with internally threaded boresarranged in line. rod 74. having its ends oppositely threaded is arranged in said bores and is provided with a centrally arranged milled disk 76. liy turning the threaded rods 74 the sections (38. 7t) may be adjusted to or from one another. The sections (38, 70 may be connected to the main receiver by pins 78 upon the hub 12 entering slots 80 in said sections. The free end of the auxiliary receiver may he su 'iported in any convenient way.

In the operation of the machine shown a top lilt upon being pushed from the top lift plate of the con'ipressing machine curved end 'l'oremost by the ejector 2 passes on to the carrier 42, which. as shown in Fig. 3. is then in an approximately horizontal posilion. 'lhe Illh'fill are engaged by the curved end of the top lilt. so that it is deflected into central position in case the ejector 2 fails to advance it in theprecisc path desired. The movement of the top lift into position upon the carrier occurs at approximately the end of the downward movement of the head 1. As the head 1 rises to compress another top lift the carrier is moved pivot ally by the chain 50 into an upright position at the entrance to the receiver. The curved guides 54 engage: the sides of the top lift in its upward movcmcnt and guide it. into the open end of the receiver. .'\s the carrier reaches the end of its upward movement in which it is a iproxinnttely llush with the end of the receiver the top lift is inserted in the open elul of the receiver. In its movement into the open end ol' the receiver the top lift advances the contents of the receiver and passes by the springs as. In the downward movement of the head 1 the carrier returns to its initial receiving position, so that it is in position to 1'eceive another top lift at approximately the end of said downward movement. As the top lifts accumulate in the receiver they are advanced into the auxiliary section. From time to time the auxiliary section may be disconnected from the main section and carried with its contents to the sorting table. By inverting this any iliary section the top lifts are conveniently deposited in a row on edge upon the table in positit'm to be sorted, the lifts in the construction shown being so arranged that as the auxiliary section is inverted they are deposited upon their breast edges. This in sures their maintaining their register with each other in the row.

it will be seen that top lifts or heels which have been stacked by the machine shown herein are in proper relation to be supplied conveniently to magazines. so that if should he desired to employ magazines to store blanks. for example. in a heel attaching or other machine, my invention would form a useful adjunct to such a machine in' facilitating the supply of heel blanks to the magazines. .\lach1nes embodying the present invention may also be used to advantage in arranging coinpressed heels or top lifts in convenient form for packing-for example Where they are produced as separate articles of manufacture. c
